It is the original name used for the current Rodagon WA lenses. The specs
are the same as the WA. If you send me your address I can send you the
current brochure.

It is possible on older lenses that they are slower than the current ones.
Since you did not tell us focal length or speed it is difficult to answer
your question any other way.

The WA series is 40mm, 60mm, 80mm and 120mm. If your lens is longer than
this it is a not an enlarging lens.

"The Rodenstock enlarging lenses Eurygon have the same optical design (6 elements in 4 groups) as the Rodagon-WA Lens.
The Eurygon was produced until 1985. The difference between the Eurygon and the Rodagon-WA is the mechanical barrel.
The Rodagon-WA has a barrel with a pre-set aperture."
